The probability of one occultation is small and it yields no directional information. The probability of a single small KBO occulting more than one star on its traverse of the Milky Way is negligible. The space between the stars is just too great. Even if it were to occur, likely years apart, there would be no way to ascribe the two events to the same KBO.

Well, this is interesting-

Looks like there is an opportunity to check this out...

Will Sirius Disappear on February 18th?
By: Bob King | February 13, 2019

On Monday night observers in parts of Mexico, the western U.S., and central Canada may see the occultation of a lifetime when a tiny asteroid momentarily blots out the night sky's brightest star.

The predicted occultation path has shifted south and east:

The original path was calculated using the center of mass of the system, not Sirius A.

I'm not sure what you're checking out. This is an already known asteroid whose orbit is well plotted and whose occultation is predicted in advance.
